It sets out the worldview of a natural scientist, who had a significant impact on the development of modern physics. For those who want to know more, for those who dare to find out exactly what the paradox of Schrödinger's theory is, for those who want to know what life is from the point of view of physics, the great scientist wrote his last and best work.
